Essential Laptop Accessories

Mousing options: Laptops don't have a traditional mouse. Find out if the laptop includes a touchpad, nub, or both. You may even get lucky if a seller throws in a mouse. Mouse options are optical, wired, wireless, and Retractable Mini Mouse.
Bluetooth: Some laptops support a short-range wireless networking technology called Bluetooth. If you have a Bluetooth-enabled PDA or cell phone, you may want a laptop that can talk and exchange data wirelessly with your other electronics.
Extra Battery: If you plan to plug in to a power source most of the time, battery life won't concern you too much. If you depend on your battery to keep your laptop up and running for long periods of time, ask your seller how long the manufacturer expects the battery to last. You may want to invest in a second battery to keep with you in the classroom or on the road.
Docking Station: A docking station allows you to connect your laptop to a standard keyboard, mouse, monitor, and printer. It stays plugged in and powers your laptop so you conserve battery power.
Carrying case: If you plan to take your laptop out and about, you'll need a laptop carrying case.
Cable lock: Most laptops have a security slot, but not all of them come with a lock. If you want a lock, look for listings that include them. You can also buy cable locks separately
